IMPROVEMENT IN SEED-DRILLS.

Specilication forming part of Letters Patent No. 2 L7 l 5, dated October 5, 1858.

To all whom fit may concern:

Be it known that I, WV. IRVIN WILLITS, of Milton, in the county of Wayne and State of Indiana, have invented `a new and useful Improvement in Seed-Drills; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon and made to form a part of this specification.

Similar letters nlrefer to like parts of the improvement.

The nature of my invention consists in the combination and arrangement of receding drillplows and corrugated rollers, making the frame to which the receding drill-plows are attached adj ustable,so that the grain may be buried at any required depth in the ground by arranging the drill-plows to work parallel either with the ridges or depressions of the corrugated roller.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation, reference being had direct to the accompanying drawings, of which- Figure l is an isometrical view of the iinproved seed-drill. Fig. 2 is a vertical sectional elevation of the same.. Fig. 3 is an isometrical view of the seeding-cylinder, together with section of concave plate. Fig. 4 is a plan of the scraper for keeping the roller clean.

A, Fig. l, represents the corrugated wooden roller, made hollow, and provided with end pieces, B, made ot' cast-iron. The roller A is attached to the frame F by means of arbors passing through the frame F at t'.

The hopper H is made very similar to hop pers in seed-drills in common use. The compartment 7c in the hopper H is made to carry tools in. The bottom of the hopper H is provided with the concave supply-plate P. (Shown in Fig. 3.) rlhe plate P is made with the openings or slots s, to allow the seed to pass down into the pockets g, and thence through theconducting-tubes t and drill-plows t to the ground. The pockets g are made of cloth, leather, or indiarubber, stitched together in the form shown, the edges being nailed to the sides of the hopper H. The conducting-tubes a are made of india-rubber or other elastic substance.

r represents an iron rod, made to support the conducting-tubesaand prevent them from coming in contact with the roller A.

F represents the wooden frame-work of the drill.

Z represents the adjustable frame-work, to which the receding drill-plows t are permanently attached. The frame Z is attached to the frame F by means of a staple-hinge at E, and is made with a loose tenen-joint at o, so as to allow lateral motion to the frame Z when it is required to change the position' of the drillplows t.

c c represent the chains which support the adjustable frame Z and prevent the drill-plows t from running too deep in the ground.

It h represent hooks attached to the frame F to receive the chains c c, and when it is de sired to change the position of the drill-plows the chains are moved from one hook-lt h to the other.

b represents a belt passing around a pulley attached to the end of the roller B and over the seeding-cylinder u, so that when the roller A is made to revolve by forward mot-ion ot' the drill the seeding-cylinder u is also made to revolve and the seed made to pass to the ground.

u in Fig. 3 represents the seeding-cylinder, provided with grooves NV and recesses d. The grooves W are made for small grains and the recesses d for corn, so that by slipping the plate P until the openings s are directly over the grooves W the small grain or seed is carried continuously to the drill-plows; or, it' the openings s are over the recesses d, corn will be deposited upon the ground in the required places for hills.

V represents the arbor of the cylinder u, and is made to fit in the frame F.

G in Fig. 4 represents a scraper attached to that part of the frame F which is behind the roller A, and is made to keep the roller A clean from earth, straw, Src.

P in Fig. l represents the pole to which horses are attached.

I claim nothing for the mode 0I"v feeding, as chains c c, and the hooks hh,a,11 arranged and I :un aware that similar devices are in eoinoperating substantially as hereindescribed,

mon use. for the purposes set forth.

/Vhat Ielaim as my invention, and desire to Y secure by Letters Patent, is W IRVIN WILLIIS' The arrangement and combination of the Witnesses: corrugated roller A, the adjustable frameZ, H. E. CLIFTON,

the receding drili-plows t, the supportng- GEO. W. L. BICKLEY.
